Joining SySOS

  • If you are an Oxford undergraduate interested in doing a summer internship on any of the above research directions (or anything else) get in touch.
  • If you are finishing your undergraduate/masters degree and you want to apply for a DPhil (PhD) or MSc by Research in our group, then please contact us sooner than later to discuss possible projects. Note that there are several Centres of Doctoral Training that are relevant to our research, especially the Interdisciplinary Bioscience DTP as well as the EPSRC CDT in Autonomous Intelligent Machines and Systems. If you have a strong academic background, the chances of securing funding for your studies are higher the earlier you apply. Note that applications need to follow the Postgraduate Admissions guidelines.
  • There are several other routes for joining SySOS, mainly through fellowships. Please contact us to discuss.

Current and Previous Externally Funded Projects

  • European Space Agency project with GMV (Spain), NGC (Canada) and the University of Leicester, "Worst-Case and Safety Analysis Tools for Autonomous Rendezvous Systems".
